ITS#1998, zero-length attr vals

Back to this issue again; the crash is actually an assert() because the
result
of normalizing a single space is a zero-length string. It seems we need to
remove these asserts and return a failure code, or just accept the
zero-length
strings. What's the right thing to do?
